If you worry about that, you would completely shit bricks at classic car shows.

Fire sleeve is pretty cheap for the legit eaton/aeroquip stuff. Of course its a major function > form thing since it only comes in orange. I normally buy stuff like that from plumbing monkey.

Hey, I have a CBR600 F2 Streetfigter project also! We can chat about them some time!

My CBR is named FiFi. Which stands for Forced induction Fuel injection. The two big projects I am doing to make her more fun..... It sure will be nice to get rid of those carbs. :wavey:

LS1 Carburetor V.S. Computer Performance Test - Super Chevy Magazine

tl;dr carbs make 462hp, efi 482hp

Not to mention throttle response, idle quality, and overall driveability.

I'm quite sure even a big cam could be tuned out with the factory PCM. We've come a LOOOOONG way since ford EEC-IV!!



That's a friend of mine's LQ9 powered Caprice running a factory PCM. Quite the cam it has... ;) (I don't care either way, Carb'd LSx > myshitty4bangercar any day!)


How the hell DID you cut such a clean hole in the hood??????

Those dont look like they're the eaton/aeroquip fire sleeve. Black one does look pretty close to the real deal, but not quite since its too glossy. AEROQUIP FIRE SLEEVE from Aircraft Spruce

Everyone gives me shit for having that stuff on my car. They say the color is horrible.

They are right. But better to have ugly heat shielding than pretty melted hoses.

If you had an equal budget, invested in an adjustable choke carb, and spent the required time to tune the carb, you would get a whole lot closer to that 482 horsepower.

They never said how much time they spent on the tuning process, or if they run the carb with the stock jetting. There is not that much difference between what a carb will make and what EFI will make. The real difference is the fact that EFI is much more consistant and now easier to work with.

soviet 10-09-2012 05:18 PM

All good points. It was more aimed at OPs claim that "nothing but a carb and high rise intake when compared to the stock set up yielded close to 100 crank horsepower on a stock ls1"

Still... not bad for a 17 year or something along those lines.

Brush up on your reading skills before you assert knowledge of something. My oil pump randomly failed, a common problem on 98' ls1's. I spun some rod/main bearings, none of it was any fault of my own, and yes I was 17 when I started building the car. I made some silly mistakes along the way and have learned a lot since then as we all through the car building process/life experiences, but I never made any mistakes serious enough to cause my engine to "blow".

Welcome.

Thanks for the welcome/compliment, I'd be interested to see your bike. To be honest I can't tell if you're being facetious or not. You're converting an f2 to run fuel injection? Why not just start with an f4i? Anyway if you are doing that more power to you, sounds radical.

All that expensive aftermarket efi stuff isn't stock and costs a lot more then my carb'd set up. But yes as I've said many times in this thread, ultimately efi is better and more expensive.

That was a sweet run man, what system did he use to tune the stock ecu?

That hole in the hood was cut by my father using this with a cut off wheel:

At closer examination it's not as nice as it looks from afar but it's pretty close to a perfect circle

Very true.

That claim is correct, do more research if you still refute it, but thanks for that link

I will probably switch over to steel braided when I go to efi

Thanks for the input everyone

Semantics. I read that thread years ago man, I don't remember specifics. All I know was it went broken. Still impressive, IIRC it didn't take you that long to assemble everything together. I have an FD roller at the hangar, been there for years and haven't even started my ls swap in that except gutting it, and selling my drivetrain. lol

So any future plans?

Thank you, yes I work fast especially when I have funds readily available, unfortunately that hasn't been the case since I initially built the car. If I had the money right now I'd get boss frog frog arms, an autokonexion trunk lid with the huge lip, roll bar/half cage set up, quieter exhaust with electric cutouts, stiffer springs for the teins, and of course efi; probably all FAST stuff and have it professionally dyno tuned.

Get back to your FD man, that's my favorite unibody factory body style. If my wildest wishes were granted I'd have a wide body fd with a 4 rotor setup

dk wolf 10-10-2012 01:54 AM

Meh... FDs are cool...
Mine stateside didn't last too long. I had it running for about 2-3 months.. put it on the lift, yanked the guts out, sold em... and well... yeah. I'll go back to it whenever I'm back stateside every now and then and do little shit. Got a ls2 to put in it, but the old man decided it would better be put to use in the sand rail. So she sits.

Came to Japistan.. decided why the fuck not, got another FD. Been headache after headache, finally got every single problem fixed on it, went single turbo and was pushing over 400hp and loved every minute of it... except gas.

Sold it, and pending purchase on a miata out here.

They're cool cars, not for the faint of heart. Paranoia pays, and shit always breaks. Just the nature of the beast.

I'd hate to own a 4 rotor, would sound insane, but I'm done with rotary motors honestly.

You don't get out of accusatorily misrepresenting what a person has done by calling "semantics," you piece of shit.

Thats what I thought when I read his response. His initial comment was just a random untrue attack for seemingly no reason that could have served to damage my reputation had it not been exposed for being the lie that it was, but I try not get "mad" over the net. Glad someone besides me called him out. Any way, its been cleared up, alls well that ends well, no beef etc

My uncle worked with/on a lot with rotaries over the years and he shares the same feelings as you so I understand. Anyway if you make any progress put it in your build thread so I can say I know your stupidity and lack of common sense caused all the problems you stand to incur. JK jk, but seriously I'm interested in seeing a 400hp rx-7 and potentially an ls2 powered one

It runs now, working out a few bugs but here is a vid/some pics. Also have added a corrugated plastic radiator shrouding box since the pics
